Detective Eleanor Voss arrived at Ravenwood Manor just as the morning fog began to lift from the cold estate grounds. Inside the grand foyer, a single candle burned very low beside the lifeless body of the wealthy industrialist Charles Ashworth. A silver letter opener protruded from his pale chest, and his wide eyes remained frozen open in silent, terrible surprise. The murderer had left no visible footprints, though the freshly polished floor bore one faint smudge near the marble stairs. Eleanor knelt down slowly, noticing a torn piece of crimson silk clutched tightly within the dead man's stiff, cold hand. Somewhere upstairs, a grandfather clock chimed seven times, and the distant sound of footsteps echoed through the long, dark hallway. Every guest had gathered in the drawing room, each wearing an expression that carefully mixed shock with quiet, calculating fear. One of them, Eleanor knew, was lying, and she intended to find the truth before the killer would strike again.
